Format JSON without uploading text.
Paste JSON, validate structure, and copy formatted or minified output from this browser. Payloads stay on this device while you prepare API, config, and support snippets.
Privacy-first by default
JSON formatting runs client-side. The workflow avoids server upload routes, account requirements, filenames, pasted payload collection, and user identifier analytics.

How to use it
- 1
Paste JSON text
Add the object, array, API response, or config snippet you want to review. The text stays in the browser session.
- 2
Format for reading
Run formatting to add indentation and line breaks so nested objects, arrays, and values are easier to inspect.
- 3
Minify when needed
Switch to compact output when the JSON needs to fit in a request body, environment value, fixture, or documentation example.
- 4
Copy the result
Review validation messages, then copy the formatted or minified output for your editor, ticket, test, or API client.
Common use cases
Security and privacy
Browser-side JSON handling
JSON snippets often contain tokens, endpoints, customer records, or internal configuration, so the formatter keeps the workflow local to the browser session. Frisbly does not need a server upload route for the pasted text and does not require an account. The page is designed to avoid collecting the input content, filenames, user identifiers, or payload values for analytics. You should still remove secrets before sharing a formatted result in tickets, chat, documentation, or public examples. Treat copied output as data you control.
Supported inputs and outputs
Supported JSON inputs
- JSON objects and arrays pasted as plain text.
- API responses, webhook bodies, fixtures, and config snippets.
- Formatted output with indentation for review.
- Minified output for compact request bodies and examples.
FAQ
Does the JSON formatter upload my text?
No. Formatting and minifying happen in the browser session, so the pasted JSON does not need to be sent to a Frisbly server route.
Can it validate JSON syntax?
Yes. Invalid input will surface a parse error so you can fix missing commas, quotes, brackets, or other syntax problems.
What is the difference between format and minify?
Format adds indentation and line breaks for reading. Minify removes unnecessary whitespace while keeping the same JSON data.
Can I paste an API response with private data?
The workflow is local, but you should still redact tokens, passwords, and customer data before sharing the result outside your device.
Does it change key order?
The formatter focuses on readable JSON output and does not try to semantically reorganize your data model.
Can I use the output in tests?
Yes. Copy formatted JSON for fixtures or minified JSON for request examples after reviewing that the data is valid and safe to store.
